Abstract: Abstract Photographic elements containing image-wise develo-pable silver halide are developed in the presence of an oxathioether development activator according to the for-mula :             R1A-(ocH2cH2)n-s-A -(X A )m wherein : R1 is H, alkyl, hydroxyalkyl, or R2-Y-(A"-X)m-A'-S-, A, A', and A" is alkylene, with the proviso that A is a moDovalent bond when R  is hydrogen or alkyl or hydroxyalkyl, is -OCO-, -S02-, -CONH-, or Y, Y  is ligand or complexing function of the type of -S-and -N(Q)- (Q - H or alkyl), R2 is alkyl, which may be substituted by OH, or when Y is -N(Q)-,  R2 together with Q may represent the atoms needed to complete a nitrogen-containing saturated ring, n  is at least 2, ard m is O or 1.      The development activators can be used in black-and-white development or in colour development.  They can be incorporated in the photographic material or in the deve-lopiL- solution.     In reversal processing they can also accomplish the task of the second exposure or of the fogging agent to render the silver halide remaining after the first deve-lopment developable.

Abstract: TUBULAR EXTRUSION APPARATUS AND METHOD    ABSTRACT A flow distribution system for a side-fed tubular extrusion die improves the uniformity of resin distribution around the die annulus.  The die has a toroidal chamber surrounding the die orifice into which the molten resin is fed from one side, and a plurality of ports through which the molten plastic flows out of that chamber toward the die annulus.  The cross-sectional area of each of the ports is gradually increased from a point adjacent the entry of the molten resin to a maximum cross-section at a-point 180° from the resin entry point.

Abstract: ABSTRACT OF THE DISCLOSURE         A figure toy which includes a unique actuating mechanism which cooperates with a novel shoulder assembly which allows the toy to emulate a shrug or a wave and to perform other functions of the same sort in a very realistic manner.  The shoulder assembly includes a member which pivots about one end when it receives pressure from the actuating mechanism.  The other end of the assembly is attached to an arm.  Thus, the motion of the shoulder assembly moves the shoulder upwardly and inwardly simulating very closely the raising of the human shoulder such as occurs during a shrug or a wave.  The arrangement allows one or the other or both of the shoulders together to be raised.

Abstract: A B S T R A C T            The invention relates to conductive elements and their preparation.  The novel elements comprise a support (prefer-ably a flexible polymeric film support) and randomly distri-buted fibres (e.g. glass fibres) which are partially embed-ded in the support.  Solid electrically conductive particles are adherent to the protruding portions of the fibres, forming a conductive layer.   Such elements are prepared by applying a dispersion of conductive particles (preferably an aqueous dispersion of carbon particles)  to a substrate comprising a support and random fibres partially embedded in the support and partially protruding therefrom, followed by solidifying the dispersion.   The elements are particularly useful as heaters.  A typical heater is illustrated in the Figure.

Abstract: ABSTRACT OF THE DISCLOSURE       A novel dry image forming material comprising in one or more layers on a support (a) a non-photosensitive organic silver salt oxidizing agent, (b) a reducing agent for silver ions, (c) a silver halide component or a silver halide-forming component, (d) a toning agent and (e) a lipophilic binder, characterized by the inclusion of a specific 2-(2'-hydroxy-phenyl)benzotriazole compound having bulky tert-butyl or tert-amyl groups at its ortho- and para-positions relative to the hydroxyl group in a layer containing the component (a).  The dry image forming material of the present invention has high storage stability prior to use for image formation. When the dry image forming material comprises a combination of a silver salt oxidizing agent-containing layer comprising the specific 2-(2'-hydroxyphenyl)benzotriazole compound and a reducing agent-containing layer comprising a high impact acrylic resin as a binder material, the material is remark-ably improved in storage stability of raw material in the dark or under light with wavelengths of 450 nm or more and the stability of a latent image, and shows minimized varia-tion in image quality with heat development conditions.  When the dry image forming material comprises, as the component (a), a silver salt of long chain fatty acid having 16 or more carbon atoms and, as the component (c), a silver halide component including silver iodide or a silver halide-forming component capable of forming a silver halide component including silver iodide, and further comprises (g) an oxidizing agent for free silver, (h) a photoreactive halogeno oxidizing agent and, in the layer containing the components (a), (c), (e) and (f), (i) a specific cyanine spectral sensitizing dye, the material is of the post-activation type and spectrally sensitized without sacrificing the storage stability of raw material.

The charge pump and an associated integrator are used to produce a first approximation of the input waveform and the DAC and an associated detuned slew-rate filter are used to maintain the first approximation in long-term conformance with a more accurate second approxima-tion. Spurious aberrations in the second approximation are  integrated over  several  steps of the input bit stream, thereby minimizing their adverse impact on the relatively true first approximation.
